      Hello,

      this question is probably best suited for @dc42

      1.What is the custom input shaper and how will it be different from the others ?

      2.Will it be possible to damp different frequencies on x and y with the a) the same input shaper or b) with different shapers ?

      3.When do you think, you release the first beta firmware for duet3 + sbc + lc1 v1.1 with the new shapers?

      TiA

      Kindly Regards
      Frederik

        Work is progressing, and the intention is to have a shorter cycle for 3.4, so more info will be coming soon.

          1. The custom shaper will let you define the acceleration steps and durations yourself, to support types of input shaper other than the built-in ones (currently ZVD, ZVDD, EI2 and EI3).

          2. The first beta will only support a single shaper. However, some of the shapers cover a fairly wide band. We may add support for separate X and Y shapers later, at least on Duet 3 (there may not be enough RAM to do it on Duet 2).

          3. I am aiming to release the first beta at the end of this week, but whether that happens depends on how many other things interrupt my work on input shaping.

            @dc42 That are great news 🙂 I'm excited
            independent shapers for the duet 3 would be an amazing feature !

            Wouldnt it be possible to offload more task to the raspberry ?

              Good idea, I once built a MCU cluster which had a shared swap-drive combined from several RAM drives. The limitting factor was the Gigabit bandwidth which doesn't apply here.
              That would also allow us to copy daemon.g into RAM drive and call it from there more frequently (no SD-card wearout)

                Most users run standalone, and our goal is to support input shaping in standalone mode.

                  perhaps a lot more people would consider using the sbc mode on duet3 boards, if it would offer more features / functionality as right now .

                  most people dont want to hassle with another level of complexity, only to add wifi and offload the webapplication with a few plugins.

                  Im personally looking forward what the future will bring. My Duet 3 is Running in sbc Mod + Lc1 v1 almost a Year now with very little trouble, while riding the unstable branch the whole time 🙂

                    @dc42 +1 for separate frequency between X and Y (also on my duet2wifi?! 😃 ). Really trying to stay away from Klipper for my Voron 2.4 but the speed improvement with input shaping is tempting me a lot!
                    However we will be happy with everything you came up with. Thanks for your hard work!

                        Yea, I would also like to see different frequencies for X and Y, even on my CoreXY toolchanger, the X frequency is almost twice as high as Y...

                          @frederik It is much better to implement it in stand alone if it is possible. The capability of running stand alone is a big selling point for me, not having to wait for the printer to boot and being able to just cut power is a killer feature for me.
